Homes built properly,
DS Kamica builds new homes, extensions and loft conversions across Northamptonshire, with our own electricians and heating engineers on every job. One team, one programme, one fixed price.

What we build
Six services, one company. Whether it is a new house or a new boiler, the same standards, the same project manager and the same paperwork at the end.
New builds
Detached homes, self-builds and small developments, from groundworks to keys.
Refurbishment
Whole-house renovations, structural changes, kitchens and bathrooms.
Extensions
Single and double storey, side return and wrap-around extensions.
Loft conversions
Dormer, hip-to-gable, Velux and mansard conversions with en-suites.
Electrical
Rewires, consumer units, EICRs, EV chargers and lighting.
Plumbing & heating
Boilers, heat pumps, central heating, underfloor heating and bathrooms.
Every trade under one roof
Most building projects slow down when the builder is waiting for an electrician or a plumber. Ours don't, because they work for us.
- Electrical work certified to BS 7671 and notified under Part P
- Gas and heating work by Gas Safe registered engineers
- A single project manager from first visit to handover
- Building Regulations applications, inspections and sign-off handled for you
- A written, itemised price with changes agreed before they happen

How a project runs
The same four stages whether you are converting a loft or building a house.
Free consultation
We visit, listen to what you want, look at the property and talk through budget, timescales and any permissions needed.
Fixed, itemised quote
You receive a written price broken down by stage and trade, with a programme. Changes are always priced in writing before they happen.
Build
One project manager runs the site. Our own electricians and heating engineers work to the same programme, and you get regular updates.
Handover
We walk the finished work with you, fix any snags, and hand over certificates, warranties and building control sign-off.
You will know us on site
Branded vans, uniforms and PPE on every job, so you and your neighbours always know who is working on your home.
